Struct ProjectileRef 

pub struct ProjectileRef(/* private fields */);

A projectile of the open world (vanilla’s Projectile), narrowed with host.projectile: arrows, tridents (a player’s too), firework rockets, thrown items, fireballs, wind charges, skulls, shulker bullets and mods’ thrown types.

Implementations

impl ProjectileRef

pub fn owner(self, host: &dyn Host) -> Option<EntityRef>

Side: server. Projectile.getOwner: the owner as a resolved entity. None for no owner, one that is gone or in another level, or a stale handle.

pub fn pickup(self, host: &dyn Host) -> Option<ArrowPickup>

Side: server. AbstractArrow.pickup, for an arrow or a mob’s trident.

pub fn pierce_level(self, host: &dyn Host) -> Result<i8, PierceLevelError>

Side: server. AbstractArrow.getPierceLevel: the signed byte stored by vanilla.

pub fn base_damage(self, host: &dyn Host) -> Option<f64>

Side: server. AbstractArrow.getBaseDamage, for an arrow (a trident’s is fixed).

pub fn critical(self, host: &dyn Host) -> Option<bool>

Side: server. AbstractArrow.isCritArrow, for an arrow.

pub fn set_owner( self, host: &mut dyn ServerHost, owner: Option<EntityRef>, ) -> bool

Side: server. Projectile.setOwner. False for a stale projectile or owner, or an owner that is a fishing hook (a trident a player threw takes a player only). Does not touch leftOwner.

pub fn deflect( self, host: &mut dyn ServerHost, deflection: Deflection, by: Option<EntityRef>, new_owner: Option<EntityRef>, by_attack: bool, power: [f64; 3], ) -> bool

Side: server. Projectile.deflect(deflection, by, newOwner, byAttack, power), with power per axis, through Projectile::deflect for the projectile list (the engine path gameplay uses). REVERSE draws one float from the projectile’s own random; AIM_DEFLECT uses by’s look and MOMENTUM_DEFLECT its normalized known speed, and both change nothing without by. The new owner is set, then onDeflection: a hurting projectile’s acceleration power is 0.1 by an attack, else halved. A wind charge refuses for its first five ticks, with no change and no draw. A trident a player threw and a rocket turn the same way (no acceleration power). False, and nothing changed, for a stale projectile, by or owner, a non-finite power or a refusal.

pub fn set_pickup(self, host: &mut dyn ServerHost, pickup: ArrowPickup) -> bool

Side: server. Sets AbstractArrow.pickup. False for a stale handle or a projectile that is not an arrow or a mob’s trident.

pub fn set_pierce_level( self, host: &mut dyn ServerHost, level: i8, ) -> Result<(), PierceLevelError>

Side: server. AbstractArrow.setPierceLevel: stores the signed byte without clamping.

pub fn set_base_damage(self, host: &mut dyn ServerHost, damage: f64) -> bool

Side: server. AbstractArrow.setBaseDamage. False for a stale handle, a projectile that is not an arrow, or a value that is not finite.

pub fn set_critical(self, host: &mut dyn ServerHost, critical: bool) -> bool

Side: server. AbstractArrow.setCritArrow; clients see the flag at once through the entity data. False for a stale handle or a projectile that is not an arrow.

pub fn entity(self) -> EntityRef
